HYDROCARBON-BURNER FOR BRICK-KILNS.

SPECIFICATION forming part of Letters Patent No. 784,126, dated March '7, 1905.

Application tiled lApril 6, N03. Serial No. 151,225.

To ft/ :nimmt it 11mg/ concern.-

Beit known that I, JOHN SeHUns, e citizen of the United States of America, residing et Los Angeles, in the county of Los Angeles and Stetevof California, have invented certain Improvements in Hydrocarbon-Burners for Brick-Kilns, &c., of which the following is o specification.

My invention relates to Ineens for atomiz ing end breaking up henvy hydrocarbons and mixing therewith a sufficient quantity of steam ond air to insure the ready thorough combustion thereof and to such Ineens articularly edapted for use in burning bric A further object of the invention is to ro- `fide such ineens in such form that the b sstlarne therefrom may be directed es desired ond in which the mixed steam and oil as they emerge from the burner are sdmixed with atmos heric sir and drawn into s. surrounding hoo by the suction crested by the blast.

Other sind further objects and ends in View will hereinafter appear from the detailed deseripltion of construction and operation.

T e invention consists ingeneral in the constructions and combinations of parts, all as hereinafter described, and particularly pointed out in the claims, and will be more readily understood by reference to the aeoompanying drawings,`forming a. psrt of this specification, in ivluch- Figure l is n longitudinal sectional view of o burner einbodyinT my invention. Fig. II is a pian View thereof@ the im@ n n of Eig. I. F10'. HI is n plan View thereof on the line III Illj of Fi". I. Fig. IV is a. partiel side View of o brieliiln, showing the burning-tunnels 'provided with hydrocarbon-burners embodymg my invention. Fig. V is e transverse sectional view thereof on the line V V of Fig. IV.

As shown in the drawings, 2 represents the moin bod of on ato1nizing-burner into the bose 3 o which enters from one side the steam-pipe 4, communicating with the duct 5, which 1n turn communicates into the central chamber 6 of the body 2. An oil-pipe 7 communicates throuh the port 8 into the central duet 9 in the zbose 3. The outer end of the duct 9 is preferably closed by a remov able plug 10, by ineens of which access tney he had to the duct 9 for the purpose of eleoning. Into the outer or forward end of the duet 9 is threaded the oil-pipe 11,\vhicl1 extends through the chamber 6, as shown, and prfjeets throu h the closed end 12 of the o f 2 and e s iort distance beyond the end thereof. Said closed end has perforetions 2.2, permitting passage of steam therethrough. The outer end of this oil pipe or tube 11 is contracted in the form shown.

-13 represents a. hood, which is preferably circuler in cross-section and has a. portion 14., which is also preferably circuler in cross section and located axially Within the hood. The portion 14 virtuell forms e short tube, one end or portion of W rich, 16, is closed ond provided with a perforation 19, through which projects the contracted discharge ond of the oil-pipe 11, and the other end is open and provided with s. thread adopted to engn e and thread upon the outer or'forwnrd en of the body2. An expansion-chamber 17 is formed between the end 12 of the hody 2 end the portion of the hood and en ennulsr steam-dischar e slot is provided between the periphery of the disehor eend 18 of the oiltube and the woll of t e portion i6. As shown, this annular discharge-slot conforms to the taper of the end 18, so as to forni e converging outlet surrounding the oil-outlet. The steam emitting from the expansionchelnber 1? through this discharge 19 is directed inwardly into the body of oil emitted from the oil-pipe 11, andes the steam exponds into the oil the oil is thoroughly broken up and etomized. To enable the ull effect of this expansion and convergence of the steam into the oil, it is necessary that the oil-out let be free, as shown-thnt isl without any obstruction by valve or similar ineens against which the oil and steam would strike and interi'ere with the forward movement thereof. The body of oil being corn ietely surrounded by the ini/vm'dly-projected,v annuler converging current of steam, the thorough otomizn tion thereof is insured. The portions 14 :md i6 are connected with the mein body of the hood by means of ribs 20, preferably formed integral therewith and with the moin body of the hood. As shown, the wall of the hood flares outward from the ribs 20, giving the forward portion of the hood a conical forni, the space within the wall oll the hood being greatest at its outer end. The portion of the hood projecting rearwardly from the ribs 2() also flares out\\fardly, as shown. Both ends of the hood are open, and air may pass freely from the rearward end through and out the forward end. 21 represents auxiliary air-inlets in the wall of the forward portion of the hood. The closed end 12 of the body 2 is provided with a series of ducts or ports 22, through which the steam may pass from the chamber 6 into the chamber l? and then out through the discharge-outlet 1?).

23 represents a suitable oil-supply pipe. The oil-sup ily pipe 23 is suitably connected with the oil-pipe 7, as by a union 25. The steam-pipe 24 is preferably similarly con nected with the steam-pipe 4, so that the position of the burner may be adjusted as desired.

The burner is connected with the pipes and 24 by means of branches 23 and 24', which preferably rise vertically a suitable distance and arc then bent laterally, preferably one farther than the other, and then toward and in alinenient with each other to the unions. By connecting the burner in this manner the pipes 23 and 24 can lie side by side on the ground, as shown in Figs. 4 and 5, and the burner will occupy a position where it can be conveniently manipulated and regulated, and the flame can be thrown in the desired direction-do\\inward, upward, or horizontally. The burner is )ivotally mounted on said branches with its pivotal axis in alinement with said branches, so that it can be turned freely in angular iosition, and, moreover, the burner exten s radially from its pivotal axis, so that a change in angular position does not necessitate any movement of translation or lon itudinal movement that might be undesira le.

26 27 represent valves by means of which the su ply of oil and steam may be regulated.

In urning brick it is necessary that a small heat be provided at the commencement of the burning for ten or fifteen hours, after which an increased heat is desired. By the use of myhood a small flame may be maintained, the hood protecting the flame at the burner-tip from any rush of airblowing out the flame. The hood taking in air at the side of the body and behind the point of admixture of steam and oil insures a sufficient supply of air and prevents blowing out of the flame. At the commencement of burning the flame is preferably rojected down upon bricks or stones on the ottom of the tunnel. When the bricks surrounding the tunnel have been partially burned, it is desirous to increase the heat, and a better effect can be produced by projecting the flame from the burner upward. I therefore so construct nl v burner as to provide for this d( change of direction of the flame.

The forward wall of the hood is outwa flared, so that all requisite space pro for the burning vapor without any su por projecting against the wall of the i avoiding any condensation thereon, amo avoiding carbonization on the hood.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- 1. In a h drocarbon-burner, a hollow cylindrical bo y provided with means for feeding steam thereto, and having its forward end closed and provided with longitudinallyarranged erforations, a flaring hood on thc closcdlen of said body having a central portion open at one end to engage and fit over the forward end of said cylindrical bod f and having a perforated wall at its forwar end, said hood being provided with ribs connecting it with sai central portion and thesaid central portion having a chamber between its ends forming an expansion-chamber in communication with the perforations of the body and ofthe central portion, and an oilpipe through said body with its forward end projecting through the perforation of said central portion.
